Aussie bird missing flight? (3)
I believe the answer is:
emu
This might be a double definition.
'aussie' is the first definition.
(bird native to Australia)
'bird missing flight?' is the second definition.
'emu' can be an answer for 'bird' (emu is a type of bird). I am not sure about the 'missing flight?' bit.
Can you help me to learn more?
(Other definitions for emu that I've seen before include "it'll never fly!" , "Flightless Aus. bird" , "Ostrich-like bird" , "Native Australian bird" , "Physics unit" .)
